The GTO, which debuted in 1984, is the first of Ferrari's storied halo cars, and helped clear the way for some of the automaker's most revered models, including the F40, Enzo, and LaFerrari. Like those car, the GTO paired a timeless look with boundary-pushing performance. It's also the rarest of its class of Prancing Horses, with just 272 examples rolling off the line between 1984 and 1987.1985 Ferrari 288 GTOThe example up for bid, which was one of the first 200 built, is also a true beauty. Its muscular composite and Kevlar exterior is finished in a glossy, factory-correct shade of Rosso Corsa, though the car did spend a few years, toward the beginning of its life, painted silver, according to the listing. It rides on a set of staggered-width 16-inch Speedline multipiece wheels. The interior, meanwhile, is covered in black leather upholstery and features air conditioning.The roots of the GTO, like so many of Ferrari's other halo cars, can be traced back to motorsports, in this case the then-new FIA Group B category. Developed to meet the class's homologation rules, the vehicle is powered by a mid-mounted 2.9-liter twin-turbocharged V-8. The mill produces 389 hp and 366 ft lbs of torque, all of which is routed to the rear wheels via a five-speed manual gearbox, and redlines at 7,700 rpm. The car can sprint from zero to 60 mph in just fives seconds brand new and hit a top speed of 179 mph, though we can't imagine the car's next owner will ever push it that hard. Mileage shouldn't be a sticking point with a car as exquisite as the GTO, but this example has just 14,000 miles on the clock and also comes with Ferrari Classiche certification.Inside the 288 GTOWe imagine there are quite a few collectors out there who would like to add this 288 GTO to their collection. They can expect to pay up for the right to do so. With eight days left in the auction, bidding has already reached $6.75 million.AdvertisementAdvertisementClick here for more photos of the 1985 Ferrari 288 GTO.Best of Robb ReportThe 2024 Chevy C8 Corvette: Everything We Know About the Powerful Mid-Engine BeastThe World's Best Superyacht ShipyardsThe ABCs of Chartering a YachtSign up for RobbReports's Newsletter.
